To change percentage soil moisture on a weight basis to percentage soil moisture on a volume basis, the following calculation is given: % moisture by volume = % moisture by weight × bulk density of the soil. When calculated for a depth of 12 inches, this value indicates water in inches per foot depth.
Formula Breakdown. The soil moisture content calculation formula is: soilMoistureContent = ( (wetWeight dryWeight) / dryWeight) * 100. Where: wetWeight is the weight of the soil sample when it is wet (measured in grams). dryWeight is the weight of the soil sample after drying it (measured in grams).
You can calculate water content in the soil by taking the soil from the earth and weighing it. Then dry up the soil in the oven and weigh it, then apply the soil moisture content formula to know the moisture percentage in the soil.

This term refers to the entire quantity of water in the ground’s pores or on its surface. The moisture content of soil depends on such factors as weather, type of land, and plants.
The desired soil moisture content depends on the field capacity (FC) and the permanent wilting point (PWP). FC means how much water the soil can hold after the excess drains off. It displays the balance of water and air in the ground’s pores. There is not enough oxygen if the moisture percentage is too high. PWP reflects the temperature threshold b...
How to calculate moisture content of soil? There are several methods. They differ in the data source that is used for this. In general, you can single out gravimetric (or direct) measurement, analysis using soil moisture sensors, and remote sensing.
You can determine soil moisture content for plants with several tools. The choice depends on the characteristics of a particular area, but here are the most popular devices. Tensiometers.They are tubes filled with water to measure the water stress in the ground. They take readings from the root zone of the crops. The main disadvantage of tensiomete...

Apr 28, 2021 · How to Calculate Soil Moisture Percentage: To calculate the soil moisture percentage accurately, it’s essential to follow a methodical approach. Start by collecting a representative soil sample from the specific area you’re studying.
Calculate the moisture content of the soil by subtracting the weight of the dry soil from the weight of the moist soil, and then dividing by the weight of the dry soil. Although the measurement is simple, it is important to determine soil moisture content in order to better understand soil characteristics.
Nov 4, 2022 · Laboratory. Measuring the Percentage of Moisture in Soil Samples. Nov. 4 2022. Why is % moisture important? The weight of a moist soil consists of the weight of the dry particles of soil plus the weight of the water within the soil.
